Codebooks and Documentation
- Webdoc, the NSFG’s interactive online codebook, was deactivated as of 12/31/20. Public-use file indexes (Appendix 1a, 1b, and 1c linked below) can be searched to find variable names or identify relevant variables based on key words in variable labels. The section letters noted in the file indexes correspond to the sections of the codebook, so the file indexes indicate which codebook PDF will contain your variables of interest.

Design and Data Collection Methods
Beginning with the release of data for 2011–2013, detailed information on the survey design and operations, weighting, and variance estimation was compiled in four documents available on the NSFG website. These documents replace the “Series 1” and “Series 2” reports published by NCHS for the 2006–2010 and earlier releases, which can be found within the NSFG’s “Publications and Information Products” pages. The survey design and all related aspects were planned with the entire period 2011 to 2019 in mind, thus are consistent from release to release. The documents below provide information on survey design and operations for 2015-2017, and reflect only minor changes and updates.

Variance Estimation Examples
Each of the PDF files below provides programs and output in SAS and STATA for three examples of variance estimation for the 2015–2017 NSFG data. These examples cover some of the basic types of variance estimation you may do in your analyses. See also the section “Sample Weights and Variance Estimation” in the 2015–2017 NSFG User’s Guide pdf icon[PDF – 982 KB] for more information. If you have any questions about any of these examples, please e-mail the NSFG staff at email@example.com.

Other Data Files
In addition to the 2015-2017 NSFG public-use data files, researchers may access two additional types of restricted-use data files available only through the NCHS or Census Research Data Centers (RDCs).
Restricted-use analytic variables: The analytic variables available in this file were suppressed or modified on the public-use data files to further protect the identity and confidentiality of the survey respondents. The variables are described in Appendix 7 of the User’s Guide.
Contextual data: The 2015-2017 contextual data file consists of four variables: CASEID, the State FIPS code and County FIPS code of the respondent’s address at the time of interview, and the State FIPS code of the respondent’s address at the time of the previous Census. These geographic variables are only available through the NCHS and Census RDCs due to the increased risk of deductive disclosure of individual respondent’s identities when such geographic variables are linked to the survey data. FIPS codes can be used to merge external data with the 2015-2017 NSFG public-use files.
For more information about using these data, including options on accessing the RDC and associated charges, visit the RDC website.
